Photon mapping simulates light refracting through transparent or 
reflecting off reflective objects onto other surfaces...if you don't 
have anything for them to show up on, you are just wasting time shooting 
photons. All of the surfaces in this image appear to be either 
transparent or reflective, with nothing for the caustics to have much of 
an effect on.
